$5/TB/month actually sounds pretty competitive. I was curious about B2, but it’s currently around $6–7/TB, so it wouldn’t really save you anything on storage alone.
Hetzner Storage Box seems more interesting if you don’t specifically need S3-compatible object storage.



The important distinction to me is whether clipboard access is user-initiated or happens silently in the background. Explicit paste should stay frictionless, while background reads are where tighter controls make sense. If GrapheneOS can enforce that boundary without adding an iOS-style prompt every time, that seems like a strong compromise.
